[pierpaolovannidocplanner]

Hello, i'm installing otpauth using Yarn 4
I use Webpack 4 as bundler but i have the following error during compilation:

[3] ERROR in ./node_modules/otpauth/dist/otpauth.esm.js 970:28
[3] Module parse failed: Unexpected token (970:28)
[3] You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

It seems that the optional chaining (?.) operator is not supported in your setup, it does not seem to be a problem with OTPAuth.
